Car-Dispatcher Communication / Hall Button Failure

If the communication link fails between the car and dispatcher the car's status will be shown as
malfunction (MLF). If the car is on normal operation and capable of running it will register its
highest unlocked car call. After arriving at the top floor, it will enter all odd car calls and stop at the
floors in the down direction. It will then go back to the highest floor and register all even car calls
and stop at these floors in the down direction. This 'block operation' will maintain service to hall
calls. When the communication link is restored the car will be place back on normal (NOR) status.
If the HBF input to the dispatcher goes off this indicates a loss of power to the hall call push
buttons. The cars will be sent the HBF status by the dispatcher and will operate the same as a loss
of dispatcher communication.
If any hall call cannot be answered by the cars in the group that are currently in service and not
showing an FLT status that hall call will be canceled. This is done to alert passengers that their hall
call request will not be answered in a timely fashion.
